What is a basic drug?
Therefore, basic drugs (like bupivacaine, pyrimethamine) are more charged inside the cell than outside. The cell membrane is permeable to non-ionized (fat-soluble) molecules; ionized (water-soluble) molecules cannot cross it easily. In an acidic medium, basic drugs are more charged and acidic drugs are less charged.
What is difference between medicine and drugs?
